I do like this design, but I like the Aztec Rising Sun, too. Too bad it's not on the shirt. Is there a reason you couldn't work it in somehow like you have it, with maybe uneven rays so it's not the box-shape that everyone loathes?

I like it but I would've liked it better with the sun... You could put it in and fade the rays into non existence.... btw I would gradually increase the width of the rays.
I'll give you 4/5 for now but with the sun I would buy it (with a 5 of course).
Good luck!
